NuClide Research · 2026-05-02


Summary

The North Kalimantan Province Government (Pemerintah Provinsi Kalimantan Utara) exposes an Ollama node at ip-103-156-110-80.kaltaraprov.go.id (103.156.110.80). The node runs cloud proxy subscriptions and a live account takeover URL. Notable: one local model is a Qwen3.5-27B fine-tuned via knowledge distillation from Claude 4.6 Opus, running on a provincial government server.

Findings

F1: Account Takeover via Live Claim URL (CRITICAL)

Querying deepseek-v4-pro:cloud returns a live Ollama Connect claim URL:

{
  "error": "unauthorized",
  "signin_url": "https://ollama.com/connect?name=7a3686b3df54&key=<base64>"
}
  • Username: 7a3686b3df54 (MAC address / container ID)

F2: Claude 4.6 Opus Reasoning Distillate on Government Server (HIGH)

Jackrong/Qwen3.5-27B-Claude-4.6-Opus-Reasoning-Distilled-GGUF is a Qwen3.5-27B model fine-tuned to replicate the reasoning patterns of Claude 4.6 Opus. Running on a provincial government IP at Q3_K_M quantization (approx. 11–13GB). This model is accessible without authentication to any internet actor.

F3: Tool-Calling Model Exposed (HIGH)

gemma3-it-qat-tools:27b has function-calling capability. Tool-enabled models on unauthenticated government infrastructure expand the injection surface, attacker can inject a system prompt that chains tool calls to government resources.

F4: CVE-2025-63389 Injectable (CRITICAL)

v0.13.4. All six models injectable via unauthenticated /api/create.
